Project Details

Project included the culvert replacement of a concrete encased I-beam bridge located on, and connected to, the downstream end of a brick culvert. The outlet of the structure was through floodwalls erected in the City of Johnstown due to prior devastating flooding. This project also required the relocation of water, gas, sewer, and aerial utilities.

The new structure is a cast-in-place concrete rigid frame having a clear span of 18’-0”. The outlet of the culvert tied to the downstream floodwall was removed and a portion of the wall was replaced. The overall project length, including approach roadway improvements, was 300’-0”.

This complex culvert replacement project used partial width construction to maintain traffic. Two lanes of traffic had to be maintained during construction due to impacts of an adjacent parking garage ingress and egress, a densely populated area, and route which serviced an adjacent hospital, school, and several businesses.


For over 20 years I have had the privilege of working with Keller Engineers and their staff of surveyors, and civil and structural engineers on over $150 million worth of work. During these project relationships and partnering opportunities, my architectural teams have received nothing but premium professional services and courtesy towards my own staff, clients and prospective clients with stellar attention given to building and site details, client responsiveness and peer respect. I look forward to many more teaming opportunities and urge any other architectural firms, municipalities or clients who have not worked with Keller Engineers to do so. You will be pleasantly surprised! Richard L. Karcher, AIA, NCARB
